The day we’ve all been waiting for has arrived. Today the ReThink911 campaign officially launches. Over the next month, tens of millions of people in 12 cities around the world will see the ads that thousands of you made possible with your hard work and generous donations.

But this campaign is way more than just these ads. It’s the educational materials we distribute, and it’s the tens of thousands of people—and one day millions of people—who raise their voices in support of a new investigation into the events of 9/11.

We kick off our people-powered educational campaign by asking you to take two vitally important actions:

1) Watch the newly released official ReThink911 video narrated by Daniel Sunjata—then forward it to all of your friends and family and everyone else on your contact list, and share it on Facebook and Twitter using the buttons below the video player. Let’s make this video go viral!

2) Sign the newly unveiled ReThink911 International Petition. When this petition reaches one million signers, it will be delivered to the Head of State of every nation that had citizens who died in the attacks of September 11, 2001.
